i2 Claims. (CI. 58-19) Matter enclosed In heavy brackets II 1 appears inthe original patent but forms no part of this rehsue My inventionrelates to alarm clocks and particulariy but not exclusively toimprovements in electric alarm clocks.

Ordinary alarm clocks are equipped with bells or bumers which emitaudible signals. Such clocks are of no value whatever to a person who isdeaf and in many instances fail to'awaken persons of normal hearingunless the alarm is very loud. In any event, the suddenawakening o! asleeper by a loud noise, such as the clamorous ringing of a bell,produces a distinct shock on the nervous system and, where other personsare sleeping in proximity to the alarm, they are also awakened. Y

The principal object of my invention is to, provide an alarm clock whichwill first give a visible alarm signal comprising an electric light and,in the event that said light fails to function, will, after the lapse ofa predetermined interval following the time when said light should havebegun to'function, give an audible signal. Another object is to providesuch an alarm clock having means for effecting an intermittent flashingof the light alarm which many experiments have determined willinvariably awaken a normal sleeper within an interval of from one tothree minutes. A further object is to provide a, simple device of thischaracter which may. beincorporated in any alarm clock but which ispreferably associated with an electric alarm clock.

With these objects in view my invention ineludes the novel elements andthe combinations and arrangements thereof described below andillustrated in the accompanying drawing in which- Fig. l is a frontelevation view of an electric clock embodying my invention;

Fig. 2 is a fragmentary perspective view showing a portion of the sideand rear of an electric clock mechanism and illustrating the controlsfor the visible and audible signals;

Fig. 3 is a fragmentary perspective view ofthe controls for the signalsincluding a switch; certain parts which would obscure essential detailsof the control being omitted;

Fig. 4 is a diagram of the electric wiring; and

Fig. 5 is a more orflless schematic view of a thermostat element foralternately making and breaking the circuit through the visible signalto produce a flashing thereof.

Referring to the drawing---v i is the case of an electric clock having asweep second hand 2, a minute hand '3 and an hour hand 4. The hour hand4 carries a pointer 5 which indicates on the graduated disc 6 the timefor which the alarm is set; it being understood that this disc may beturned independently of the clock hands by means of the alarm settingbutton I (see Fig. 2) which is understood to proiect through the back ofthe clock in the usual specification: matter printed In Italicsindicates the additions made by reissue 2 way. The clock motor is asynchronous motor and preferably of the self starting type so that, inthe event of a power interruption, the clock will start as soon as thepower comes on. A small circular opening 8 is provided in the lace ofthe clock, and pivotally mounted behind this is a red disc 9 whichbecomes visible only upon an interruption oi the power to indicate thatthe clock has been stopped and that the time indicated thereby is notthe correct time. Mounted on top of the clock is the visible signallingdevice l0, here shown as an ordinary incandescent lamp bulb which ismounted in the socket ll having the usual switch l2 for turning thelight on or oil so that it may be used as a reading lamp if desired.However, it is to be understood that the lamp may be placed anywhere andthat the switch l2 need not be associated with the lamp socket. In fact,if the lamp is to be used solely as a signal or alarm, the switch I! maybe omitted.

Referring to Figs. 2 and 3, i3 represents generally the clock motorwhich comprises the coil I4, the pole pieces i5 and I6 and an armatureenclosed in the casing i'l. One of the pole pieces it has an extensioni8 which alternately attracts and releases the armature I! of avibrating element 20 to produce a buzzing sound. when. the clock is inoperation with the power on, a constant vibration of the element 20would take place unless it were mechanically restrained and hence means,which will hereinafter be described, is provided, whereby vibration ofthe element 20 is prevented at all times when the alarm control is inthe oil position.

2| is'the alarm gear which is driven by the clock motor and is to beunderstood as making one turn in [2 hours. Mounted upon the alarm gearshaft 22 is a cam 23 having a, notch 24 therein (see Fig. 3). [The cam23 cooperates with. [normally engages] the extension 25 of .the armatureportion IQ of the vibrating element 20, as a follower and prevents itfrom vibrating unof the clock is the ofi and on control forjth'e alarm.Thus, in the position of the bnttb "11,25 shown in Figs. 2 and 3 thealarm will as unded when the proper time is indicated byitheclock.

- In other words, the button 25 is shown in alarmon position. The button26 is connected to the lever 21 which is slidably mounted in the clockframe members 28 and 25 and carries a cam 30 which is adapted to passunder and engage the end of the armature l9 when the button 26 is pushedinwardly, or to the left as shown in Fig.

3 and thus to maintain the armature 19in non- .vi brating position. Theflat spring memberisl which is secured to the frame member 29,; as

in switch 42 which forces the 3 shown at 32. is provided with aspherical depression 38 therein which is designed to coop r with theopening 34 in the lever 21 to form a stop motion for the lever when itis pressed inwardly.

So far, the clock mechanism "which I have described is a standardmechanism forming part of almost all electric alarm clocks as now man-'ufactured. To this mechanism I propose to add my visible alarm signaland so to incorporate it with the audible alarm signal given by theelement it that my. visible signal will first be given and then, afterany predetermined interval to be fixed by the manufacturer of the clock.will be followed by the audible signal. To do this I fix a second cam 3|having a notch 35' therein tothe shaft 22 of the alarm gear II as shownin Figs. 2 and 3. Cooperating with the cam I! is a pawl or follower IIwhich, as illustrated, is part of the bell crank 31 which is mounted torotate freely on the shaft 38. The other arm 3! of the bell crank isprovided with a threaded passage ll adapted to receive the adjustingscrew ll. 42 is an electric switch of the single pole, doublethrow typehaving the terminals 0, 4t and I. The switch is adapted to be actuatedby the push button it which is spring biased by meansof' the compressionspring ll, shown schematically in Fig. 4, to maintain the terminal itnormally in electrical contact with the terminal ll. However, when thebutton it is pressed against the compression of spring ll by means ofthecoopwhich may be. and preferably is, a so called flasher "buttonwhich will begin, in effect, alternately to make and break theelectrical circuit in whichit is installed within a few seconds alarmgoes oil, the lamp is not lighted it will beeration of the adjustingscrew Ii therewith, the

terminal 43 is held in electrical contact with th terminal.

Referring now to Fig. 4,4! and are main power lines to which the clockit may be connected by a plug and socket in the usual manner.Bearinginmindthattheterminalflis normally held in contact with theterminal 44 by means of the coaction of the follower [pawl] bell crankwith the button ll, the light ll may be turned on oroif by means of theswitch II. Thusitmaybeusedasareadinglamp.

Inoperation,thecam ll,insteadof thecam It.issocorrelatedwiththealarmsettingdiscl that if, for example, the 10thhour graduation onthediscissettocoincidewiththepointer I on the hourhand, the follower [pawl] II will fall into the notch 36' when the handson the face of the clock indicate 10 o'clock. It is to be understoodthat the spring which normally forces the button 46 downwardly, asviewed in Pig. 3,

into the notch w itwillbeforced into this notchby the release ofcomprusion on the spring button 48 downwardly.

Now. referring more particularly to Fig. 4, when thefollower[pawl]flentersthenotchinthe cam ll, the bell crank will allow the button 0 tomove to the right, as viewed in Fig. 4, thus breaking the contactbetween terminals 43 and 44 and establishing contact between theterminalllandtheterminaltl. Ifthelamp "were lighted at this time itwould be momentarily extinguished by the breaking of its normal lightingcircuit. However, the terminal 4| issimultaneomlyelectricallyconnectedtotbeterminalllof the lamp through thethermostatic element ll sin to flash within a few seconds afterterininals It and are brought into contact.

In Fig. 5 I have shown in a diagrammatic manner how the thermostaticelement ll operates. 55 and It are the terminals of the device. Theterminal II is electrically connected to a fixed contact point 51 and isalso connected to terminal 58 through the high resistance coil 58 whichis wound about the bimetallic element 59 [39] carrying the contact pointll adapted to cooperate with contact 51. When the points are separatedcurrent flowing through the resistance heating coil it heats thebimetallic element 59 causing it to flex or warp and bring contacts BIand ill together. When this occurs, terminals 55 and it are directlyconnected through a resistance of negligible magnitude, the highresistance coil BI is shunted, and the bimetallic element to cools andassumes its original form, thus separating contacts I1 and 80. Currentthen flows only through the heating coil 58 and the cycle is repeated.It will be apparent that the circuit through the lamp and thethermostatic switch is never completely opened by the action of saidswitch because, when this circuit is otherwise closed by switch 42,current will always flow through the resistance heating coilll. However,the practical effect of theoperation' of the thermostatic switch, asevidenced by the flashing of lamp II, is the same as though the lampcircuit were alternately closed and opened, and I have referredthroughout the specification and claims to the thermostatic switch as acircuit making and breaking means. The thermostatic switch does actuallymake and break the circuit which lights the lamp although anothercircuit of .very high resistance is immediately established through thelamp filament when the lighting circuit is broken.

Many tests have indicated that the flashing of the light II will awakenthe average sleeper within an interval of three minutes or less.However, in the event that the lamp has burned out or has been removedfrom the socket, the cam which turns continuously in the direction ofthe arrow It will shortly release the audible alarm which will continueto function until the extension passes out of the notch 24 in cam 23.Obviously, the notches in the cams 2.3 and 35 may be disposed at anydesired time interval apart so that the light signal may continue forany desired interval before the audible signal is released.

Unless some means were provided for preventing the follower [cam] 36from dropping into the notch 35' in cam I! when the alarm control is inthe off-position, the flashing signal would be given every 12 hours; thetime depending upon the settin of the alarm. To prevent this I providethe bell crank 31 with an arm 53 which cooperates with a cam N on thealarm control lever 21 when said arm is pushed inwardly. Thus, when thebutton It is pushed in, the cam holds the vibrating armature II ininoperative position and the cam 54 cooperating with the arm It holdsthe follower [pawl] 38 in inoperative position.

From the foregoing it will be apparent that I have provided, by a rathersimple modification of .the ordinary electric alarm clock, an alarmclock giving both a visible and an audible signal and while, asillustrated, the invention is shown as incorporated in an electricalclock, it may be incorporated in any alarm clock.

In addition to its utility asan ordinary alarm clock the device may beused as a desk or reading lamp, and when so used it may be set to give aflashing signal at any desired time. It makes no difference whether thelamp I is lighted or out at the time the signal is given because, thelight control switch II is automatically shunted and a new circuitestablished through the lamp.

The device, whether it be used as an alarm for awakenin a sleeper, anappointment signal, or

otherwise should prove aboon to persons who are v nervous and detestnoiseot any kind.

By the term electric clock" as used in the claims, I mean to includeonly clocks in which the timing mechanism is actuated by a synchronousmotor.

While I have described my invention in its preferred embodiment it is tobe understood that the words which I have used are words of descriptionrather than of limitation and that changes within the purview of theappended'claims may be made without departing from the true scope andspirit of my invention.
